Have you looked at SK, Proto, Wright, Williams, or Armstrong?
You may also try checking out your local pawn shops. At the one I visit, the above named brands sell for less than snap on or craftsman.
If you want some affordable US made sockets, perhaps you should check out MasterForce (Menards house brand) or Allen (seen these at Menards and Fleet Farm). IIRC they are both made by Apex. (Same Company that Made Craftsman sockets)
